Compare total cost of renting vs buying over time with appreciation, tax benefits, opportunity cost, and breakeven year analysis.
Renting and buying are decisions whose costs unfold over years, and this tool projects both paths on the same timeline. It applies an appreciation rate to the home's value, credits the mortgage interest tax deduction at your tax rate, charges the down payment an opportunity cost at your assumed investment return, and reports the breakeven year: the point where owning's cumulative cost falls below renting's. The common mistake is comparing this month's rent with this month's mortgage payment, which ignores rent growth, property taxes, insurance, maintenance, and the costs of buying and selling. The result cuts one way: renting wins short stays, buying wins only if you stay long enough.
Each year, the renter pays rent that grows at an assumed annual rate and keeps the down payment invested. The buyer pays the mortgage, property tax, insurance, and maintenance, then at the end of the holding period receives the home's appreciated value minus the remaining loan balance and sale costs. The tool compares the cumulative totals year by year, so a single breakeven point can be located.
The down payment is not treated as spent; it is valued at the investment return the user assumes, which credits renting with investing the money instead. The mortgage interest deduction is applied at the user's tax rate, lowering the effective cost of the loan. The breakeven year is the first year cumulative buying cost falls below cumulative renting cost; before it renting is cheaper, after it buying is.
Then you are on the renting-cheaper side of the comparison. Buying concentrates costs up front - closing costs, taxes, and a down payment that is no longer earning investment returns - so the breakeven year is normally several years out. Shorten the holding period in the tool to the time you actually expect to stay, and compare the two totals at that point.
Only if you actually itemize. The deduction reduces taxable income only when your total itemized deductions exceed the standard deduction, which a large mortgage makes likely but not guaranteed, and property tax deductions are capped by law. If you are not sure, run the calculator both ways; the gap between the two results shows how much of the buy case rests on the tax benefit.
